The SGT is capable of testing any industry standard geophone element or string conﬁgurations whether in the ﬁ eld or in a workshop environment. This highly versatile, state-of-the-art geophone tester can be used as either a hand-held, battery-powered system or a desktop system.
SGT is capable of testing sensitivity, coil resistance, natural frequency, damping, distortion, tilt, ambient noise and several others. The SGT measures the ambient noise prior to running the tests to ensure valid data. The acceptable level of noise can be user-deﬁned or calculated by the system. The SGT displays the average noise level in real-time, allowing the operator to detect and eliminate the source of ambient noise. Furthermore, all measurements are compensated for temperature.
